Description 

One of only 2 tunnels in the 17-tunnel Clinchfield Loops segment that is completely lined with concrete. Although it is slight skewed, configuration of the tunnel in relation to the three nearest it, suggests that Speedy Tunnel was designed to prevent a much more difficult skew of the line around a small rock outcropping of the Blue Ridge, necessitating a speed reduction of trains ascending and descending the mountain; hence the name "Speedy" Tunnel.
